The B110 uses a steering gearbox integral (one unit) with the steering column. Optionally available was a collapsible-column unit for safety in case of a crash. The collapsible column was standard for USA models. The gearbox is a relatively fast 15:1 ratio with only 3.3 turns lock to lock, and used a quality recirculating-ball type system.

Overview
For modification-required swaps, see Steering Gearbox Swaps
The B210 and B310 units both have a seperate gearbox and column, joined by a flexible coupling. But these gearboxes will not bolt to the B110 subframe connection.
- B120: Type RB41N, 15.0:1 3.3 turns
- Available in standard or collapsible column types
- B210: 15.0:1 3.38+ turns
- B310 A12: Type RB43N 16.4:1 3.5 turns
- B310 A14/A15: Type BR45L 15.0:1 3.2 turns
- B310 Australia uses 16.4:1 model for all engine (per Gregory's)
The steering arm is fastened to the gear by an M16 nut, with 24mm hex.
Gear
Datsun 1200 uses RB41N (Recirculating Ball) steering gear, which is also known as Worm and Sector. RB type is still used by fullsize cars and trucks as it is stronger/more durable than rack & pinion gearboxes.

Shaft Bearings
Two ball bearing assemblies hold the column/worm shaft in place.

Interchange
Only Datsun 1200 gearbox interchanges. Made in Japan through 1994, and in South Africa through 2007.
B110 mounts with one front bolt, two rear bolts. PB110, B210, B310, 510 mount with two front bolts, single rear bolt. Cherry uses Rack & Pinion, so it does not interchange.
Some parts inside the gearbox, including seal and bearings, interchange between B110 RB41N and the smaller B210 (early RHD) box and the smaller B310 box -- type RB43N. B210/B310 BR45L boxes share zero parts with the B110 box.
Service
U-joints
Datsun 1200 does not use a separate steering column; it has the column as one piece (integral) with the steering gearbox.
B210 and B310 use a separate column with a rag joint.
Datsun 510 and 240Z use a U-joint
